A convex optimisation approach to optimal control in queueing systems
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2017)Convex optimisation and max-weight are central topics in networking and control, and having a clear understanding of their relationship and what this involves is crucial from a theoretical and practical point of view. In ... -
Fault localization in Distributed Adaptive Systems
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)Modern systems that execute in ubiquitous environments must be adaptive in order to maintain an acceptable quality of service. As in traditional distributed systems, faults in such systems are likely to propagate across ... -
Decentralised detection of emergence in complex adaptive systems
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)Emergence is a hallmark of Complex Adaptive Systems (CAS), where non-deterministic interactions between agents can give rise to emergent behaviour or properties at the system level. The nature, timing and consequence of ... -
Peer assisted multicast streaming on-demand applications
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)On-demand multimedia streaming applications allow users to select and view content at a time of their choosing and to control the playback of this content. This level of control typically requires that each user receives ... -
Towards the development of a clinically effective interoperable epilepsy electronic patient record
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)eHealth including Electronic Patient Records1(EPRs), is a key enabler to effectively support the coordinated approach to chronic disease management (CDM), including epilepsy, by improving information flow between patients ... -
Transfer function optimization for volume visualization based on visibility and saliency
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)Volume data is widely used in scientific and medical research, and volume visualization techniques aim to provide effective and flexible methods for analyzing and exploring complex structures in such data. However, obtaining ... -
Colour transfer and shape registration using functional data representations
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2017)In this thesis we propose new colour transfer and shape registration methods based on the robust L2 distance. For colour transfer, we present an approach inspired by techniques recently proposed in shape registration. We ... -
A cross-cultural exploration of online community newcomer behaviour
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)As Internet use has become globally pervasive, the literature suggests that national culture is having an impact on online community communication practices. The importance of researching national culture in these spaces ... -
Mathematical foundations of differential privacy
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2017)Sensitive personal data collected about us has the potential to give great insight into human behaviour, but it remains a challenge to publish such information while guaranteeing (i) individuals’ privacy and (ii) data ... -
Distinguishability and Web traffic timing analysis
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2017)Privacy of data transmitted over public networks has attracted much attention over recent years. Studies show that attacks based on traffic analysis enable malicious users to extract useful information about communications ... -
Global-driven service composition in mobile and pervasive computing
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)Pervasive computing environments enable access to diverse resources and services over networked computing systems. Mobile systems have the potential to be very active participants in such environments as resource providers, ... -
Translating from "State-Rich" to "State Poor" process algebras
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)Following the development of formalisms based on data and behavioural aspects of the system, there are a number of attempts in which these two formalisms are mixed together to get benefit of both paradigms. Circus being a ... -
Supporting visual diagnosis of performance problems in multi-core and parallel software
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)The shift towards multicore processing has led to a much wider population of developers being faced with the challenge of exploiting parallel cores to improve software performance. Debugging and optimising parallel programs ... -
Vectorization for accelerated gather/scatter and multibyte data formats
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2016)SIMD extensions to the instruction sets of general purpose processors have become widespread, and SIMD width and the capabilities provided by the hardware are steadily increasing with newer processor generations. This ... -
Collaboratively designing Dublin : understanding designing Dublin: learning to learn as a strategy for collaboratively developing Dublin
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)Contemporary global challenges, such as climate change, peak oil and population growth, are daunting and may, at times, seem to be insurmountable. The difficulties of addressing these challenges have been compounded even ... -
A domain knowledge driven information uplift approach for network monitoring
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)With the advance of modern network technologies, people now enjoy increased convenience whilst occasionally suffering annoyance from network issues by lacking domain expertise. In the Home Area Network (HAN), these issues ... -
Group communication for cooperative automated vehicles
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)The automotive industry has increasingly adopted computer technology to enhance the safety and efficiency of vehicles. Using sensors and electronic control systems, vehicles can become partially or fully automated, taking ... -
Temporally consistent region based video segmentation
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)This thesis addresses the problem of segmenting a video sequence in a temporally consistent fashion, so that the labels assigned to particular region remain the same throughout the sequence. Energy minimisation, and in ... -
A case study of Action Design Research for privacy risk management engineering
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2014)This dissertation presents a case study concerning the application of the Action Design Research (ADR) methodology to the development of a privacy-enhanced electronic postal system. As part of the ADR project, a model of ... -
